| 摘要 |
The present invention relates to a mono-polarized 22-beam aerial for a mobile communication base station, comprising a metal floor, at least 12 rows of parallel linear aerial arrays, at least 12 first power dividers, at least 12 second power dividers, a first Butler matrix feed network and a second Butler matrix feed network; each row of linear aerial arrays consists of at least two identical aerial radiating units. The aerial structure of the present invention forms 11 fixed directional beams in the horizontal direction, and 2 fixed directional beams in the vertical direction; the interference between the 11 beams in the horizontal direction is small, and the interference between the 2 beams in the vertical direction is small. The 22-beam aerial manufactured according to the technical solution of the present invention achieves a good anti-interference effect, has consistent performance, is easy to install, and can effectively reduce cost and better satisfy user requirements.
